state folder is not automatically created (Bug #45)
One can specify a state folder with this construct:
<state type="state" directory="c:\some\dir" />
This directory might not exist on first run of the given project and contrary to artifactDirectory and workingDirectory, it is not created automatically.
This leads to an error at the end of a build because CCNet cannot save the state of the build.
It would be nice if that directory was created automatically like the others are.
